Overview
Fix implicitly null parameter types in templates.
What this PR does / why we need it
In PHP 8.4, implicitly nullable parameter types will be deprecated. Read the RFC for more details. This change will prevent a deprecation warning once PHP 8.4 is released. It has no effect on earlier PHP versions.
Instances of this were already fixed via php-cs-fixer in non-templated code, so this is also more consistent within the code base.
